Hi again,I thought it might be great feature to import a picture as a background layer to the composition. It would be possible to calk new notes/composition grains through an existing imageand export it finally, if desired as a pdf/bmp.Maybe not a big thing

Hi, and thanks for your proposotion. Indeed, it is not too difficult to implement ; it could have some uses for the educational uses of HighC I am currently investigating. Finally, if I ever expand the features to cover "audiopaint" a la metasynth, that would be a starter.

The issue is that this would not be a feature for the beginners in HighC, as its purpose is not immediately understandable. In order to keep the simplicity of the UI, I'd have to make this possibility a tad hidden. For instance, I'd put an extra line on the Tools>View Inspector > background, that would let you enter a background image.

1- would that do cover your usage properly?2- if possible can you post the kind of picture you'd like to use as a "stencil"?

Thanks for the quick answer.Yes this could work. Just wondering if it would be possible to zoom the picture to the needed size after import. This could be interesting if you have a high resolution picture and just want to take details. I´m a bit thrilled of Sonic Visualizer, which is a great tool. Example picture is exported from SV.

FYI, I got similar feedback from someone using HighC to teach teenagers. I am currently working on implementing this for version 2.9 (version 3 being delayed till I can put some very serious work on it...)

I studied your problem a bit more - you are right, when you set the View>Show Enveloppes parameter to false, the pdf that gets generated triggers a bug in Preview.

This is not a bug in HighC, but one in Preview, so I can't fix it.

The workarounds are:

- use View>Show Enveloppes to true when printing to pdf. Possibly, turn all your sounds to "flat enveloppes" before printing the scene, then go back to - use Export as Bitmap... instead of printing to PDF. The image size will actually be somewhat smaller anyhow.- use Acrobat Reader (it sucks, but hey, at least it doesn't have this bug)

I will try to implement a workaround in HighC, that is to say, generated pdf instructions that do not trigger the Preview bug. But understand that this is somewhat out of my control, so there's no guarantee I can fix it.

What is the type of the image you're importing? Can you try saving your picture as png and importing it again?

In reporting an issue, it is often useful to provide better feedback on what you see so that I can understand what's going on. Can you read the following page: http://highc.org/forum/comments.php?DiscussionID=36 and check what error messages are written in the messages window?
